380V Distribution Box Number

A 380V distribution box is a low-voltage three-phase power distribution cabinet designed for industrial and commercial applications, typically rated for 380V line-to-line voltage and varying current capacities.

Key Features

Voltage and Phase Configuration: 380V distribution boxes are designed for three-phase systems, commonly used in industrial facilities, commercial buildings, and large-scale operations. The 380V rating refers to the line-to-line voltage in a three-phase system, which is standard in many IEC countries and compatible with 400V or 415V systems within ±10% tolerance. Current Ratings: Depending on the model, distribution boxes can handle different current capacities.

For example, the XL-21 series is rated for 380V, 800A, suitable for high-power industrial applications, while smaller models like the YNXM series support currents from 6A to 250A for general power and lighting distribution. Construction and Protection: High-quality cabinets are typically made from cold-rolled steel with electrostatic spray finishes, achieving protection levels like IP54, which safeguards against dust and water splashes. Modular designs allow flexible combinations of circuit breakers, contactors, relays, and measurement instruments, ensuring safety and operational efficiency.

Applications: These distribution boxes are widely used in power plants, manufacturing facilities, rail transit, aerospace, oil foundries, metallurgy, textile, and commercial buildings. They provide centralized control, overload and short-circuit protection, and motor control functions for industrial equipment. Installation Types: Distribution boxes can be floor-standing, surface-mounted, or flush-mounted, depending on space and operational requirements.

Floor-standing models like XL-21 and SP-XL are common in industrial settings, while modular wall-mounted boxes are suitable for commercial or residential applications. Additional Features: Advanced models may include manual transfer switches, intelligent monitoring, leakage protection, and overload protection, ensuring continuous and safe power supply even in complex industrial environments. Selecting a 380V Distribution BoxWhen choosing a 380V distribution box, consider: Rated current and power requirements of your facility.

Number of circuits and modularity for future expansion. Protection level (IP rating) for environmental conditions. Phase configuration (three-phase three-wire, four-wire, or five-wire systems).

Installation type and available space. Compliance with standards such as GB/T 7251. 3-2017 or IEC low-voltage distribution standards.

By matching these specifications to your operational needs, you can ensure safe, reliable, and efficient power distribution for industrial or commercial applications.
